*Note

specific load.
Caution
The maximum speed and acceleration values quoted can be safely achieved with
the maximum load and a high duty cycle. However in this case, some heating of
the stage may occur and dimensional stability of the stage may be affected. This
could result in less than optimal repeatability and accuracy. For cases were
repeatability and accuracy are critical it is recommended that the stage
temperature is allowed to reach a steady state before measurements are taken.
Alternatively the load, acceleration and duty cycle should be reduced from the
maximum values. Some trial and error in setting these values may be necessary
before the ideal settings are attained.
